摘要： Misalignment created during a multiple-patterning process is a serious challenge for critical dimension (CD) control and layout design in continuing integrated-circuit device scaling. A number of post-lithography misalignment correction technologies based on the shadow effect are invented for multi-patterning lithographic applications. When applied to transfer patterns from a top layer to an underneath layer, the subtractive shadow effect in anisotropic plasma etching combined with a hard-mask process, will shift the position of features such that the previously produced misalignment can be corrected. Also, additive shadow effect in a sputtering/evaporation process can be used. Misalignment correction methods allow the semiconductor industry to print sub-32 nm (half-pitch) features using the double-patterning technique with currently existing lithographic tools (e.g., 193-nm DUV scanner), therefore postponing the need of expensive next-generation lithography (NGL). The misalignment correction methods can be applied to existing lithography technologies to print features smaller than their physical resolution limits.
摘要翻译：在多重图案化过程中产生的对准是连续集成电路设备缩放中的关键尺寸（CD）控制和布局设计的严重挑战。基于阴影效应的许多后光刻未对准校正技术被发明用于多图案化光刻应用。当应用于将图案从顶层转移到下层时，各向异性等离子体蚀刻与硬掩模处理相结合的减影效应将移动特征的位置，从而可以校正先前产生的未对准。此外，可以使用溅射/蒸发过程中的附加阴影效应。不对准校正方法允许半导体工业使用具有当前存在的光刻工具（例如，193nm DUV扫描器）的双重图案化技术打印32nm（半间距）的特征，因此推迟了昂贵的下一代光刻的需要（NGL）。不对准校正方法可以应用于现有的光刻技术，以打印小于其物理分辨率限制的特征。
